Abstract: A hinge device for a portable terminal that includes a first housing and a second housing is provided. The first and second housings are connected by a hinge device at one end of the first housing, and they rotate so that the front and back faces may be reversed. The hinge device includes a first hinge base combined with one side of an end portion of the first housing, a second hinge base combined with one side of an end portion of the second housing and rotating in opposition to the first hinge base, and an elastic member providing an elastic force in a direction that the first hinge base and the second hinge base are adhered closely to each other. The hinge device facilitates a user's viewing of video, such as DMB video, and contributes to the diversification of the design of the portable terminal.

Abstract: Disclosed is a hinge unit for a compact headset, which includes a speaker housing and a microphone housing, and which can be worn on the user's ear. The hinge unit comprising: a pair of opposed side hinge arms provided in the speaker housing at one side thereof; a central hinge arm provided in the microphone housing and assembled between the side hinge arms; and a current-carrying means having a pair of first current-carrying hinge members provided in the side hinge arms, and a pair of second current-carrying hinge members provided in the central hinge arm between the first current-carrying hinge members to slidingly surface contact with the first current-carrying hinge members, allowing the speaker housing and the microphone housing to be fully detached, both mechanically and electrically.

Abstract: Method and apparatus for designating performing notes based on synchronization information are provided. After detecting meta score information from a musical score or MIDI (Musical Instrument Digital Interface) data to be performed, note position information for all notes included in an electronic score is generated based on the musical score or the meta score information. By utilizing the note position information and synchronization information, which includes the sync performance time at which each note is to start to be performed, performing notes are designated on the electronic score at each time synchronized. The synchronization information may be generated from the meta score information or the MIDI data, or may be read from a synchronization information file stored in advance. Alternatively, the synchronization information may be generated in real time by analyzing live input sound.

Abstract: Disclosed herein is a camera lens module pop-up device for a portable wireless terminal which enables insertion and extraction of a camera lens module into and from the portable wireless terminal in a pop-up manner.

Abstract: A rotation key device for a portable terminal which includes a rotation key configured to rotate in forward and reverse directions. The rotation key device comprises a base plate, which is attached, at a lower surface thereof, to an upper surface of a first printed circuit board (PCB) mounted in a body of the portable terminal. A second PCB is attached to the upper surface of the base plate and is provided with a plurality of contact surfaces. A ring-shaped washer is attached to the upper surface of the second PCB, a rotation key is attached to the upper surface of the ring-shaped washer so that it can rotate in forward and reverse directions by a force applied thereto, a contact plate is provided in the rotation key, with a plurality of contact terminals, and a fixed button is coupled with the center of the rotation key so that the rotation key is rotatable.

The rotation key device comprises a base plate, which is attached, at a lower surface thereof, to an upper surface of a first printed circuit board (PCB) mounted in a body of the portable terminal. The base plate is centrally provided at an upper surface thereof with a plurality of coupling protrusions in order to couple a second PCB, a ring-shaped washer, a rotation key, and a contact plate, to the base plate. A fixed button is coupled with the coupling protrusions of the base plate protruded from the contact plate, thereby retaining the second PCB, the ring-shaped washer, the rotation key, and the contact plate. The fixed button is centrally attached to the upper surface of the second PCB.

Abstract: A watch type portable radiotelephone is disclosed. The watch type portable radiotelephone includes a body element having upper and lower case frames; a battery pack holder including a battery pack for supplying power to the body element; a locking device for locking and unlocking the battery pack to and from the battery pack holder, respectively; a hinge connector for rotatably connecting the body element and the battery pack holder to each other; and a wrist band connected to the body element and the battery pack holder for enabling the portable radiotelephone to be worn around the wrist.
